# DIY Floaty Hydrometer

{% hint style="warning" %}
The Floaty Hydrometer is a legacy integration. It is disabled by default and only appears in device settings when previously enabled on your account.
{% endhint %}

Floaty is treated as a legacy integration in the current beta UI. The section in **Settings → Power-ups** only appears when Floaty is already enabled on your account.

## Current behavior

* If the Floaty section is visible, you can:
  * toggle it on/off,
  * copy the Floaty **ID**,
  * open **(configure webhook)**,
  * open this page via **See instructions**.

## If Floaty is already enabled

1. Open **Settings → Power-ups**.
2. Copy the displayed **ID**.
3. Configure your Floaty sender/app with that ID.
4. Start logging from Floaty.
5. In your batch, go to **Fermentation → Devices** and attach the Floaty device.

## About the Floaty Hydrometer

The Floaty Hydrometer is a DIY floating hydrometer project. It is considered a legacy integration in Brewfather -- the toggle in **Settings > Power-ups** only appears for accounts that previously had it enabled. New users will not see this option.

## Data Logged

The Floaty sends batched readings. Brewfather takes the most recent reading from the batch and stores the following:

| Field           | Description                                                           |
| --------------- | --------------------------------------------------------------------- |
| **Gravity**     | Specific gravity (SG), converted from the raw value (divided by 1000) |
| **Temperature** | Temperature in Celsius                                                |

## Configuration Options

Per-device offsets can be configured by clicking the device name in your batch under **Fermentation > Devices**:

* **Gravity Offset** -- Adjusts all gravity readings by a fixed amount
* **Temp Offset** -- Adjusts all temperature readings by a fixed amount

A **(configure webhook)** link is available when the integration is enabled, allowing optional data forwarding to an external URL.

## Logging Interval

**Never log more than once every 15 minutes.** Requests logged more often than that will be ignored.
